Mac & Jack's Serengeti Wheat is Vegan Friendly

Company email (February 2013):
"Our African Amber and Serengeti Wheat are our vegan friendly beers. No, we do do not manufacture anywhere else in the world."

Email from Brian:
"I couldn't find an email address on the Mac and Jacks website, so I called them. When I asked if their beer is vegan, the guy on the line first said, 'no', flatly. Then he asked me, 'what makes a beer vegan? I've never heard of a vegan beer.' So I explained that gelatin and isinglass are used to filter and clarify beer, and he said their beers are unfiltered and they also use no adjuncts, such as lactose. After our conversation he said, 'I guess our beers are vegan.'

However, since he didn't know what I was talking about, I think a double (or triple) check is in order."
